Gardeners' Notes:

I planted this I think two and a half years ago. Bottom part of the plant is in mostly shade, top is in the sun for much of the day. This spring it is suddenly GLORIOUS! I'll take a photo soon and post it. The flowers are HUGE.

According to Hillier' Garden Guide in the UK, this vine "needs almost complete shade." If that is the case in the relatively cool British climate, then shade would be a necessity for growing this plant in most of the US.

This has not been vigorous for us. It's all over England but either our heat or intense sun has kept it from flourishing. Beautiful when happy (and slow growing all say) but we haven't been able to make it so.
